WILLIAM ABELL BISHOP, OF NEWARK, -NEW JERSEY, ASSIGNOR OF ONE-HALF TOCALVIN TOMKINS, OF NEW YORK, N. Y.

IBARREL-HEADING AND HOOP-DRIVING MACHINE.

To all whom it may concern:

Be it known that I, WILLIAM ABELL BISHOP, a citizen of the United Statesof America, and a resident of Newark, in the county of Essex and Stateof New Jersey, have invented a new and useful Improvement inBarrel-Heading and Hoop-Driving Machines, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings.

My invention relates to that class of barrel heading and hoop drivingmachines which is intended to produce slack barrels, which are barrelsmade up as a rule with one head in place, the other head being placed inposition after the barrel is filled, and'the object of my invention isto produce a compressed air, steam, or other fluid operated machinewhich will receive staves assembled within two or more intermediatehoops and drive or press one head into place and level and drive the twochime hoops into place with accuracy, thereby avoiding accidentalpushing of the head beyond the groove made for its reception, damagingthe head, pushing one or more staves out of line, driving the hoopsaskew or beyond the edge of the barrel end or crushing the barrel,

To this end the construction and operation of my improved machine may bedescribed as follows, in connection with the accompanying drawings inwhich Figure 1 is a vertical section of the machine in a position readyto drive a barrel head into place. Fig. 2 is an end view partly insection of the same. Fig. 3 is a top plan of the upper or hoop drivingportion of the machine. Fig. 4 is a top plan with parts being brokenaway of the barrel holding and alining devices, the barrel beingomitted.

In the lower part of a frame comprising a base 1, standards 2, top piece3, intermediate piece 4:, and braces 5, and mounted on said base 1, is acylinder 6, inclosing a piston head 7, of a vertical piston rod 8,supporting on its upper end a circular plate or table 9, adapted tosupport and raise into place a barrel head A. Surrounding the cylinder6, is a frusto-conical boxing or guide 10, adapted to center a partlymade Specification of Letters Patent.

in the angular supporting and aliningplates 13, several pairs of holesbeing provided in each pair of plates, so that adjustment toward andfrom the barrel centering device may be easily eflected by withdrawingthe pivots from place, moving the enlarged ends of the arms opposite anearer or farther pair of holes and reinserting the pivots which may besecured in place by a cotter pin or other fastening. This adjust abilityallows for operation on barrels of different heights and diameter withina limited range.

To the rear side of the arms 12 are secured brackets 16, supportingcounterweights 17, and to the upper ends of the arms 12 are adjustablysecured hook ends 18, the hook ends being comparatively narrow wherethey are secured to the arms 12 and rapidly widening to form wide hooks19, which are circular or segmental in form and may be narrower or wideras desired up to a half circle, than the hook illustrated. The hook endsbeing easily removed may be readily replaced by hook ends having hooksof different width or made on a different radius. The hooks have fiatunder faces 20, and downturned edges 21, the wide flat under faces 20catching the upper edges of the barrel staves and preventing theirupward movement at the time of the application of the barrel head,which, on being raised, contacts with the downturned edges 21, just asthe barrel staves, which have been pushed slightly upward by incidentalpressure of the head against the inner surface of the barrel just belowthe croze, are stopped by touching the wide under faces 20, the distancebetween the faces 20 and the edges 21, corresponding to the distance between the ends of .the staves or barrel and the outer side of the barrelhead in the headed barrel. The head is thus brought opposite the grooveintended for the reception of its edge, is prevented from rising toohigh, and is sprung into the croze all around at the same instant. lVhen pivoted in any but the outermost pair of bracket holes, the hookarms may be held in position by slipping a short bar through the nextadjacent pair of holes under the counterweights. Usually however thearms are held manually and fall back on being released,

Leading through the base 1 into the cylinder (3 at the bottom thereof,is a pipe 22 com- I municating with a source of compressed air,

steam, or other fluid under pressure and controlled by a valve 28operated by a lever 24, preferably a foot lever. An air cook 25 at theupper end of the cylinder (5 is provided for partial relief of pressureabove the piston head 7.

Mounted between and bolted to the top piece 3 and the intermediate piece4, which in this instance are shown as large channel beams bolted orbracketed to the standards 2, is a cylinder 26 in which operates apiston head 27 and piston rod or plunger rod 28 carrying at its lowerend a presser head or plate 29. Opening into the cylinder 26 is an upperport 30 and two lower ports 31 and 31?. each connecting with a source ofcompressed air, steam, or other fluid under pressure, the upper port 30being controlled by a valve 32 and the two lower ports being controlledby valves 33 and 33 respectively, the valve 32 being controlled by alever 3i and the valves and 33 being controlled by levers and 85respectively. The levers 34 and are connected by a rod 36 made in twopieces joined together by a turnbuckle or other adjustable connection 37and are adapted to operate in unison, the lever 34: and valve 32 beingpositioned or adjusted to cut off the pressure when the lever and valve33 are positioned or adjusted to let on the pressure, both levers beinginfluenced by the handle extension 38 on the lever 35, to cause thepiston head to ascend or descend, and both levers being influenced bythe projection 39 at the opposite end of the lever 35 to cause thepiston head to ascend.

The pivotal points of the levers 3t and 35 are at 40 and 41 respectivelyin the bar 42, extending between and bolted or bracketed to the toppiece 3 and the intermediate piece l, and downward movement of thehandle extension 88 is intended to cause a downward movement of thepiston or plunger 28. Lever 35 carries a pendant 43 having thereon lugs44 and ellwhich are preferably provided with anti-friction rings orrollers and which are adapted to contact with lever the lower end of thependant being steadied by being passed through a hole 48 in theintermediate piece t, Lever 35 is influenced by the movement. of lever35 when it contacts with either lug l l or lugeland is also influencedby a ver tical sliding rod which, passing through perforation 45 in thetop piece 3,. and perforation (4:5 in intermediate piece 4, carries atits lower end a head 46 adapted to contact with the upper side of plate29 as it rises and falls and carrying in an intermediate position anadjustable combined weight and limit stop 47, adapted to abut againstthe pendant 43, move it downward and cause the valve 33 to admit anadditional quantity of fluid under pressure a few inches before the endof the stroke and after the piston head has passed port 31 which actcauses an acceleration of the pis ton heads speed, and a more powerfuland effective blow to be struck by the plate 29. A vertical sliding rod48, carrying at its lower end a head l9 also adapted to contact with theupper side of the plate 29 as it rises and falls, and carrying in anintermediate position an adjustable combined weight and limit stop 50adapted to abut against the projection 39 on the lever 35, move itdownward and cause the reversal oi the movement of the piston head 27after its attached piston rod and plate has descended any predetermineddistance, passes through a perforation 48 in the top piece 3, andthrough a perforation L8 in the intermediate piece l, and follows themovement of the plate 29. The adjustable stop 51 limits the downwardmovement of the lever handle extension 38 thus limiting the movement ofall the levers and valves in one direction. The coiled spring 52attached to the upper side of the piston head 2? prevents the pistonhead from rising too high and uncovering the port 30 of the upper valve32, thus preventing the escape of air while the machine is at rest withthe piston head raised. it also softens the end of the upstroke.

In operation the barrel (without heads) is placed over the table 9 andcenters itself on the base by means of the boxing or guide 10; a head isthen placed on the table 9; the arms 12 are brought over the edge of thebarrel; compressed air, steam, or other fluid under pressure, isadmitted through pipe 22 by opening valve 23, by pressing foot lever 2.the piston head 7, piston rod 8, table 9, and head A are lifted, thehead It pushing the barrel into touch with the wide flat under faces 20of the hooks l9 and itself being pushed into the groove or croze C; thehooks 19 and arms 12 preventing the barrel from rising too far and alsopreventing the head from being pressed beyond the croze. During thisoperation air is compressed slightly in the upper part of the cylinder6. This acts as a cushion to prevent too severe a movement of the pistonand also tends to quickly return the rising parts to their normalposition, the amount of the compression being regulated by the air orpet cock 25. After the head has been pressed into place the pressure onthe lever 24 is removed allowing the valve to exhaust and the table todrop. The arms 12 automatically fall away on account of thecounterweights. A hoop is fitted on the upper, and now headed, end ofthe barrel, and a downward movement of the handle extension 38 on thelever 35, causes compressed air, steam, or other fluid under pressure tobe admitted above piston head 27 driving the piston or plunger 28 andthe plate 29 downward, leveling the barrel and driving the hoop andalso, if desired, another hoop placed over the opposite or lower end ofthe barrel, into place. Rods 45 and 48 follow the plate 29 in itsdownward movement.

During the downward stroke of the piston head the lower valve 33 isopened to exhaust to the atmosphere while the upper valve 32 isadmitting compressed air, steam, or other fluid under pressure to drivethe piston head. An upward movement of the lever reverses the positionof these valves, the lower valve 33 admitting compressed air, steam, orother fluid under pressure under the piston head and causing the plate29 to rise, the upper valve 32 exhausting at the same time. Thismovement can be automatically controlled by the adjustable limit stop 50coming in contact with and moving the projection 39 on the lever 35. Thedownward movement of the lever 35 sets valves 32 and 33 in position forthe clownward stroke. At any predetermined point in the stroke, the stop50 can be made to strike the projection 39, reversing the position ofthe valves and causing the piston head to rise to its original position.The value of this arrangement is in the fact that the machine can beregulated to strike-asoft or cushion blow and can be made to returninstantly from any point in the stroke, as the reversing of the valvesplaces a fluid cushion under the piston head causing it to rebound andrise at once as the pressure is being relieved on the upper side at thesame time that it is being increased on the lower side of the pistonhead.

WVhen the extension lever 38 of the lever 35 is moved downward toproduce the downward stroke it engages the lower lug 44 and moves itdownward causing the lever 35 to open the exhaust port in the valve 33and at the same time with the aid of the rod 36 setting the upper andlower valves 32 and 33 for the down stroke (this position being shown indotted lines-in Fig. 2). The valves are now arranged so that the uppervalve 32 is admitting the operating fluid and both lower valves 33 and33 are exhausting to the atmosphere. The rod 45 falling with the plate29, on reaching a point where the piston head passes the port 31 of thevalve 33*, causes the adjustable limit stop 47 on the rod 45 to engagethe pendant 43 causing the lever 35 to move the valve 33 still farther.This farther movement of the valve 33 first closes its exhaust and thenadmits fluid to the cylinder through port 31*. The object of thisarrangement is to admit an additional quan tity of fluid just before theend of the stroke and after the piston head has passed valve 33*, valve33 still being open to exhaust. This gives a stroke which is even andcomparatively slow through the upper portion of the piston heads traveland the added quantity of fluid through the valve 33 gives a quick andpowerful finish blow. An upward movement of the lever handle 38 engagesthe upper lug 44 and returns all three valves to their originalposition. The lower lug 44 acts as a stop to limit the movement of thevalve 33 and the pendant 43 is guided and steadied by its lower endpassing through the intermediate piece 4.

Owing to the construction of the valves they may be adjusted withrelation to their various levers so that with the same lever movement,they may be made to admit a greater or less quantity of air up to thecapacity of the supply pipe. They are adjusted by loosening a clampwhich holds the operating levers to the spindle and then rotating theminto the desired position by applying a wrench to the squared head ofthe spindle.

The arms 12 are only held in position over the barrel until it has begunto rise. At that time the hook shape of the upper ends of the armscauses them to hook to the staves the result being that owing to theirshape they assist in spreading the staves for the reception of thebarrel head in the croze.

It is to be noted that by inserting the barrel head from the inside ofthe barrel danger of crushing the barrel and the barrel head is avoidedand a barrel head of several pieces of material can be placed as easilyand successfully as a barrel head of one piece, and that from the mannerin which the barrel is secured while heading and hooping there is nowabbling or skewing. By means of the thumb nut or screw bolt 53 thetable may be secured in a higher or lower plane, the piston rod beingscrewed up or down in the piston head and the said screw bolt 53 beingagain tightened. The valves 32, 33 and 33 are also adjustable inrelation to their operating levers and may be set to admit more or lessair or other fluid under pressure with the same lever movement. justed.
